Proto J5570 Hand Socket 2-3/16 Inch 12-point 3/4 Drive

Product Description

The PROTO J5570 is a 12-point hand socket designed for heavy-duty fastener work on 2-3/16 inch fasteners. Built from alloy steel with a chrome-plated finish, it fits a 3/4 inch square drive and meets ASME B107.110-2012 standards. At 3-9/32 inches in overall length, this is a standard-length socket suited for general-purpose wrenching in tight or open-access environments. Licensed tradespeople and experienced mechanics rely on it for consistent torque transfer on large hex or double-hex fasteners. The 12-point configuration allows more engagement positions, reducing the need to reposition the wrench during use.

This socket is appropriate for industrial maintenance, heavy equipment service, and mechanical work where 3/4 inch drive tooling is standard. It handles large fasteners commonly found on structural assemblies, heavy-duty machinery, and commercial mechanical systems. The chrome finish provides corrosion resistance for use in shops, on job sites, and in service environments where tools are exposed to moisture or shop fluids. Note that this socket is not tether capable and is not rated for use with impact drivers.

Key Features

• 12-point design allows greater engagement angle flexibility and faster repositioning
• Alloy steel construction provides strength for high-torque applications
• Chrome-plated finish resists corrosion in shop and field environments
• Meets ASME B107.110-2012 standards for hand socket tools
• Standard length at 3-9/32 inches overall for versatile access
• Not tether capable — not intended for elevated or drop-hazard work zones without separate retention measures

Compatibility

Designed for use with 3/4 inch drive ratchets, breaker bars, and torque wrenches on 2-3/16 inch fasteners. Suitable for hand-drive use only — not compatible with impact drivers or air tools.

Installation Notes

This socket is a hand-drive tool and should be used only with 3/4 inch drive hand ratchets, breaker bars, or manual torque wrenches. Always ensure the fastener is fully seated in the socket before applying torque to prevent slippage or rounding. Inspect the socket for cracks or wear before use. Keep the drive square clean and free of debris for proper tool engagement.
